[Qemu-devel] [PATCH v7 0/4] monitor: let Monitor be thread safe

[Peter Xu]

v7:
- let monitor_fdset_get_fd() return -errno, touch up qemu_open() to
  translate that into errno.  [Markus]
- touch up comment for Monitor.rs
- rebase, and torture the code a bit with qtest.

v6:
- add/drop some r-bs
- address all the comments from Markus
- rebase, and run some simple qtests to make sure nothing breaks

v5:
- collect r-bs and rebase
- move two close()s outside critical section [Dave]
- move comment to end of line [Stefan]

v4:
- fix a s/cur_mon/mon/ typo

v3:
- add comment for fields that are protected by monitor lock [Stefan]
- drop most of patch 2, only keep the protections for mon->fds [Stefan]
- add one trivial patch to add some more comments for either readline
  and cpu_get/cpu_set [Stefan]
- add protection for monitor_fdset_get_fd() [Stefan]

v2:
- cc correct people... sorry.

Stefan reported this problem that in the future we might start to have
more threads operating on the same Monitor object.  This seris try to
add fundamental support for it.

Please review.  Thanks,

Peter Xu (4):
  monitor: rename out_lock to mon_lock
  monitor: protect mon->fds with mon_lock
  monitor: more comments on lock-free fleids/funcs
  monitor: add lock to protect mon_fdsets
